KNOGKDOWN FORGE.

Application filed June 1'7, 1915.

To all whom it may concern:

Be it known that l, HENRY B. Knrrnn,

a citizen of the United States, residing'at Lancaster, in the county ofLancaster and State of Pennsylvania, have invented certain new anduseful Improvements in Knockdown Forges; and I hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, which form part of thisspecification.

This invention relates to blowers and forges and more particularly tofoldable legs for portable knock-down forges.

The primary object of the invention is to provide in a portableknock-down forge improved means for folding and locking the legs of theforge in either folded position, or in position for use, so that theapparatus can be folded into compact form for convenience in packing,shipping and transporting the same from place to place.

The invention will first be hereinafter more particularly described,with reference to the accompanying drawings, which form a part of thisspecification, and then pointed out in the claims at the end of thedescription.

In said drawings, Figure 1 represents a perspective view of a portableforge mounted upon foldable legs embodying my invention;

Fig. 2 is a vertical sectional elevation of the same; parts of the forgebeing broken away and the foldable legs being shown in differentpositions in full and dotted lines; and

Fig. 3 is an enlarged detail perspective view of a broken-away portionof one of the legs and the bracket to which it is secured detached fromthe forge body or frame.

Referring to said drawings, in which the same reference letters are usedto denote corresponding parts in different views, the letter A maydenote the forge body or frame of what is known as an Army and Navyfolding forge, which may be of the form shown, or of any desiredconstruction, and as my present invention pertains solely to thefoldable legs and means thereon for ad justably securing and locking thesame to the forge body or frame in upright or folded position, furtherdescription of the forge proper is unnecessary. In the form shown theforge is mounted. upon four foldable Specification of Letters Patent.

legs B, B, each of which may consist of a rod threaded at one end andpivotally secured at said end within the cavity of a depending portionof an angleiron bracket 0, which may be bolted or riveted to the frameor body of the forge, as shown, so as to adapt the leg to swing on itspivot into a position substantially at right angles to the bracket,underneath the body of the forge, as shown in dotted lines in Fig. 2,and be secured in such position by means of a lock'nut D, fitted uponthe exteriorly threaded end of the leg and adapted to seat against theangular end of the bracket, when the leg is arranged in a positionperpendicular to the base, or against one edge of the angle-iron whenthe leg is turned up under the forge body into the position shown inFig. 2 in dotted lines, whereby said leg may be adjusted and locked ineither of such positions. Preferably a washer E is interposed on the legB between the nut D and the pivot both for contact with the bracket endor edge according to the position of the leg. It will be understood, ofcourse, that a greater or less number of legs than four may be used,four being usually employed in forges of the type shown, although threewill suffice. In order that the leg, when thrown up into the dotted lineposition shown in Fig. 2 and locked, may touch the bottom of the forge,as indicated in dotted lines, I preferably cut away one edge of thebracket, as at 0, providing a shoulder, as at 0 (Figs. 2 and 3) againstwhich the washer E will strike when the leg is raised, and the washerbeing seated against the inclined surface 0 will securely and firmlyhold the leg in an elevated posi tion against the bottom of the forgeand when the legs are swung back into normal position, by turning thenut, the washer will be forced tightly against the angular in eithernormal or folded position. The inclined. shouldered portion of thebracket permits the leg when folded to make close contact with theunderside of the blower, as shown in dotted lines in Fig. 2, and at thesame time affords greater security against displacement than a straightedge. However, the inclined feature may be dispensed with.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A foldable self-bracing leg for a knockdown forge or the like,comprising an angle-iron bracket adapted for attachment to the forgeframe or body; and a rod pivoted at one end within the angle of saidbracket and having an adjustable locking device thereon engaging theangular end of the bracket so as to lock the leg thereto in the planethereof; said locking device being movable along the leg and adapted toengage one edge of the free end of said angle-iron when the leg isturned and lock the leg in a position substantially at right angles tosaid bracket.

2. In combination with a knock-down forge or the like, a foldableself-bracing leg consisting of an angle-iron bracket depending from'theforge frame or body, a rigid arm or leg proper having a threaded endpivoted to said bracket within the angle thereof and adapted to be swungup underneath said body into position substantially at right angles tosaid bracket, and a nut screwed on said threaded end and adapted toengage the angular end of the bracket and lock the arm thereto in theplane thereof, and to engage one edge of the angle-iron when the arm isturned substantially at right angles to the bracket and lock said arm inthe latter position.

3. A knock-down forge comprising a foldable frame or body andself-bracing foldable legs therefor consisting of angleiron bracketssecured to said body and having pendant portions and legs havingthreaded ends pivoted to said pendant portions; said legs havingadjusting devices thereon adapted to engage the angular end of thebracket when the leg is in normal position and to engage the edge of thebracket when the leg is swung into a position substantially at rightangles to the bracket, and to lock the leg in either position.

4:. I11 combination with a portable forge, a foldable self-bracing legcomprising a bracket of angle-iron depending from the forge body orframe, an arm or leg proper pivotally secured at one end to said bracketin the plane thereof and adapted to be turned up under said body,substantially at right angles thereto, and means for locking said arm ineither of said positions, said means consisting of a nut screwed uponsaid arm, and a washer interposed between said nut and the pivot bolt,said washer being adapted to engage the free end of the bracket when thearm is in normal position and to engage one edge of the bracket inanother position of the arm and lock the leg in either position.

In testimony that I claim the foregoing as my own, I affix my signaturein presence of two witnesses.
